WALL-TAPE.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed March 17, 1920. Serial No. 366,550.

To all whom it may concern:

Be it known that I, JOHN SoHUMAcnnn, a citizen of the United States,residing at Los Angeles, in the county of Los 'Angeles and State ofCalifornia, have invented new and useful Improvements in \Vall-Tape, of

which the following is a specification.

The invention relates to a flexible tape, and is especially adapted forcovering joints, fissures, or cracks in flat surfaces. The tapeembodying this invention is especially suitable for use with wall board,on plastered surfaces, and the like. Wall board is delivered in the formof plates for installation by attaching it to the wall of a rooniorbuilding to form The joints between the sections may be filled with acement putty to present a smooth surface, or strips of paper may bepasted over the joints, fissures or cracks. Fissures or cracks inplastered surfaces and the like may also be covered with strips toconceal the same. Such strips are commonly of uniform thickness and whenplaced in position, the strips project beyond the surface, shouldersbeing formed at the sides thereof. This makes. the strips visible andunsightly. It is the primary object of this invention to provide a tapeor strip, which may be placed upon and will adhere to a surface, andwhich has a thickness so distributed that no shoulders will be formed atthejunction of the tape with the surface, the two merging. .It isanother object of this invention to provide an adhesive tape of thecharacter described.

I accomplish these objects by means of the embodiment of my inventionillustrated in the accompanying drawing, in which:

Figure 1 is a perspective view showing fragments of wall board sectionswith a joint covered by my improved tape; F ig. 2

is a ers )ective view showin In improved tape applied to an otherwiseexposed edge of a plaster board unit; Fig. 3 1s a perspective view ofthe tape.

Referring more particularly to Fig. 1,'A

and B indicate units or sections of plaster board; preferablygmadeofplaster placed between fibrous covering. This kind of plaster board iswell known in the art. A joints is formed between th units A and B. Inorder to present 'a finlshed surface, the joint should be filled orcovered. For this purpose, I have sho'wn-myyimproved tape 5 placed Thistape is preferably, of fibrous material such as paper of the characterused in the covering for the plaster 1 which form in plastered walls.

board. j The tape preferably has a flat undersurface wlth anadhesiveapplied thereto.- The upper surface is preferably convexedintersecting the lower surface, so that knife ed es are. formed on thetape.

It is obvious that when the tape is placed in. position, the uppersurface thereof merges with the surface of the plaster board. A finishedsurface i thus produced wh ch has no shoulders or irregularities.

When the surface is tinted, or papered, it

appears smooth and continuous.

In Fig. 2, the tapeis shown applied to an otherwise ex osed edge of theplaster board. Units of plaster board commonly are produced with exposededges. There is an-u peer and a lower coverin of paper; but tl fe edgespresent exposed plaster It would be advantageous to cover the edgestopresent a surface with less asperities, and also as a protection againstchipping and the absorption of moisture. 0 indicates the plaster boardand 8 an edge. The tape 9 is pasted over the edge and the ends 10 and 11thereof folded over the covering sheets 12 and 13. The junction of thetape with the covering sheets is such that no irregularities in thesurface are apparent.

In the drawing, sizesare exa gerated to All of the exposed edges may becovered in this manner, if desired. The tape is also suitable forcovering cracks and fissures As the tape is preferably formed of fibrousmaterial having some resiliencyand being flexible, any'change, such islikely to occur. in the fissures or cracks will not disturb the tape ina way to make such changes visible.

It'is within the scope of my invention to taper the surfaces and form aknife edge on either or both edges of the tape.

What I claim is:

l. A tape for walls comprising a strip of flexible fibrous materialhaving an upper surface and a lower surface tapering and A intersectingin a knife edge.
